K. Avenman 1964 Bikar Atoll, Marshall Islands calling until well after dark. There appeared to be perhaps 500 in the group. They grew silent about 1 A.M. and may even have left at this time, perhaps without landing. They were never observed on the ground though they may have been scared up by our lights from a distance. Oct 17. Up about 0800. Puttered around for awhile, then George & I went up to band Sooty Tern chicks. Did 600 between us from 1100-1330. Mat 10-20 days old. Found 20 Crested Tern eggs and two chicks. The eggs resemble Sooties' but are larger and the spots not "smeared". The chick is all white, pink feet, bill. Looked like an albino Sooty chick except for the larger, thicker bill. Went for a short swim to wash off the Sooty Tern guano. The chicks imitate their parents' worst habits at the earliest possible age. Water actually hot, warmer than even I like it. After dark we descended en masse on the boobies again, first trying the club on Annumen with almost no success, then bombarding the forest edge and smashing down the descending birds with poles & nets. Returned to home base 2100. Roger & I went up to the Tern colony and banded 700 more chicks after finding it impossible
